Best Full Tower PC Case Buyers Guide – 2021 Edition

While choosing the right components for your gaming PC is a builder’s number one priority, you should not forget about the case or chassis in which you will be assembling the whole unit. 

Most people tend to overspend on the internal components, only to be left with the remainder of their budget that can only accommodate subpar or unbranded cases. We’re not saying that unbranded or lesser-known units are outright bad choices, per se, but investing in a reliable unit isn’t really rocket science, is it?

We’re rounding up the best full tower PC cases of 2021 for this article, so read along and find out!

What is a Full Tower Case?

Full tower cases are the largest available chassis for consumer-grade PCs. As such, gamers and enthusiasts opt for them over their smaller counterparts due to the sheer size they sport, some reaching more than 20 inches in height and offering spacious internals – perfect for those who want a to fit a custom liquid cooling loop inside them, or to pack a high number of graphics cards into their system. Some full tower cases can even accommodate two independent PCs in a single chassis.

Moreover, this allows the user to kit out their PC with a ton of fans, making use of the extra volume to provide an optimal level of airflow to cover power-hungry components like the processor and graphics card/s. Full tower cases can generally fit every kind of motherboard size standard, from the widely-used ATX, the rare and gigantic Extended-ATX (E-ATX), and small form factor ones such as Micro-ATX and Mini-ITX.

It features slot covers to hide any unused bays as well as keep the wires out of sight. 

While most cases have fixed power supply shrouds, which help hide the cable clutter at most, the be quiet!

This full tower case features an impressive 4-sided tempered glass layout that bares all for the world to see. Of course, since these panels will be providing weight support as well, Thermaltake has seen to it that they are made with 5mm thick walls to improve load-bearing capabilities.

Furthermore, the Thermaltake View 71 also has a great deal of modularity that allows the user to build the entire PC from the ground up with removable panels, racks, and brackets to free up space along with mounting arrays that conveniently accommodate components without having to reach for inaccessible screw points.

Corsair OBSIDIAN 1000D

If you are already overwhelmed by a standard full tower case, wait till you lay your eyes on the Corsair OBSIDIAN 1000D. This monster of a PC case is in a league of its own so much so that Corsair has decided to call it a super tower instead. It measures a whopping 27 inches in height and length, putting other full towers to shame – and for good reason. The Corsair OBSIDIAN 1000D can accommodate an E-ATX platform as well as a mini-ITX build in a SINGLE compartment. Imagine having two, fully-functional computers in one case. 

To keep things cool, the Corsair OBSIDIAN 1000D supports up to 480 mm of radiator space, even holding two of these in the front panel alone. This is augmented by an 18-fan mounting system that’s sure to keep everything cool even in the heat of the moment. You can mount these using the tool-less telescoping trays that can pop out conveniently so you won’t have to reach into the case every time you need to screw a fan or radiator in. It ranks low in the storage game, however, only allowing 5 HDDs and 6 SSDs to be installed at a time.

You also get a fan control solution via the integrated Corsair Commander Pro fan and lighting controller which you can fully utilize using the iCUE Software. Moreover, front panel connectivity is futureproofed thanks to USB 3.1 Type C Gen-2 and USB 3.0 ports for maximum backwards compatibility, outlined by RGB accents to tie in with the Corsair OBSIDIAN 1000D’s entire lighting arsenal, which of course, is showcased by the elegant smoked tempered glass panels.


  • Spacious enough to fit two systems in it
  • Excellent radiator and fan support
  • RGB aesthetics improved thanks to smoked tempered glass
  • Free fan and LED controller


  • Super heavy
  • Not a lot of customization options

Phanteks Enthoo Pro

If you happened to overspend on your components and completely forgot about taking your case into account, the Phanteks Enthoo Pro slides right in with its affordable price tag. While not as stylish as the other options, this budget-oriented full tower case has more or less the same features and functions you would usually find in this specific form factor. 

First off, the Phanteks Enthoo Pro sports a closed hard drive panel that adds load support to the case’s structure even if the HDD cages are removed, without losing out on storage support as it can accommodate a mix of internal and external drives of up to 16 units. Moreover, the case has improved clearance spacing and tolerances to provide an easy installation process for fans and radiators, especially if you want to do a push-pull setup. You can control the fans with the included PWM hub as well.

With regards to water cooling, the Phanteks Enthoo Pro has a generous internal mounting layout offering four different installation areas for units ranging from the measly 120 mm to massive 420 mm radiators for maximum cooling effectiveness. Out of the box, you get a single 200 mm front panel fan and a 140 mm rear fan, but you can mix and match your own airflow setup to get your desired level of cooling performance. To further improve the building experience, this case has integrated cable management ties to minimize cable clutter and improve overall airflow.

Because of all listed above, we believe that the Phanteks Enthoo Pro is one of the best full tower computer cases on this list.


  • Affordable full tower
  • Decent watercooling support
  • Tons of drive bays and brackets


  • Intake vents are slightly choked
  • Aesthetically plain

Cougar Panzer EVO RGB

For those who deem aesthetics to be just as important as performance, rigging your gaming PC with a full tower case like the Cougar Panzer EVO RGB is a great way to turn your setup into instant eye-candy. This case has a generous allocation of tempered glass panels to let you showcase your RGB-equipped components like graphics cards and motherboards, or the included four Vortex RGB 120 mm fans – which you can control with the included Cougar Core Box that supports up to 8 RGB fans and 4 LED strips so you can manage fan and lighting control in one fell swoop.

Apart from that, the Cougar Panzer EVO RGB allows you to outfit up to four double-slot 390 mm graphics cards – provided that your motherboard can accommodate it – if you’re planning to build a PC that can also double as a content creation machine. You also get a decent amount of storage drive support, albeit being slightly lower capacity than our previous suggestions. It ranks average in water cooling support, however, with closed-loop coolers being the most accommodated in here as opposed to the usual custom loops.

The Cougar Panzer EVO RGB also offers excellent front panel connectivity, a feature which most cases have overlooked for far too long. You get a dedicated USB 3.1 Type C connector, two USB 3.0 ports, and a USB 2.0 port for maximum compatibility whether it be modern or older connection standards. You also get handy audio I/O setup and the integrated fan controller switch where you can adjust the speed of fans connected to the Cougar Core Box on the go.


  • Spacious internals
  • Improved airflow
  • Optimal aesthetics
  • Loaded front panel connection


  • Limited watercooling support
  • Risky when you live with pets

Cooler Master H500P MasterCase Mesh

It’s expected that anybody wanting to build a gaming PC would want the best full tower gaming case to supplement all the high-performance parts that need the best cooling to run at optimal conditions. This is where cases like the Cooler Master H500P MasterCase Mesh shine, which boasts an ultra-breathable design thanks to its mesh-type front panel. As such, the front panel comes preinstalled with two massive 200 mm fans out of the box to supply cool and fresh air to heat-generating components. 

As for water cooling capabilities, the Cooler Master H500P MasterCase Mesh supports radiators of up to 360 mm in length for the front and top panels, while the rear can accept a single 140 mm radiator. While this isn’t on par with other cases that support up to 420 mm radiators, this chassis makes up for it with sheer airflow performance. Storage is on the low side, however, accommodating only two 2.5/3.5-inch HDDs and five SSDs. This is to avoid any obstructions that drive cages may pose, as they are usually positioned by the front panel, which is clearly not the case here.

Building inside the Cooler Master H500P MasterCase Mesh is hassle-free thanks to the cable management covers that tuck away your wiring mess without posing a threat to system performance. It also comes with a built-in vertical graphics card mount, with two additional rear PCIe slots allowing you to show off the RGB lighting and gaming design of its fan shroud. Top it off with a subtle gray-tinted tempered glass side panel, and you’re set to show the world your dream rig’s aesthetic swag.


  • Great airflow
  • Decent watercooling support
  • Elegant looks
  • Has cable management features 


  • A bit heavier than most full towers
  • Limited storage support

Corsair Obsidian 750D Airflow Edition

Our Corsair suggestion above may have all the bells and whistles you could possibly find in a full tower case, but even we’re having second thoughts on jumping the gun on such a pricey purchase. If you want to patronize the brand without all the glitz and glamour, try your hand at the Corsair Obsidian 750D Airflow Edition. It isn’t as aesthetically pleasing as its more premium cousin, but it gets the job done pretty well.

It sports the traditional case layout but with more room since this is a full tower variant. Constructed from a combination of solid steel and brushed aluminum, you won’t have to worry about overloading with high-performance parts, accommodating most double-slot flagship graphics cards with ease, along with extensive support for multiple fans and radiators to be installed seamlessly. Do note that cable management isn’t the best in this case, as it lacks a power supply shroud to stash your cable clutter away.

As for storage support, the Corsair Obsidian 750D Airflow Edition sports a tool-free modular drive cage system that you can remove for added real estate. This drive cage system can allow up to ten 3.5/2.5-inch and three 5.25-inch drives, giving you the option to install an optical disk drive on the upper portion of the front panel. The majority of the front panel is consumed by a low-resistance mesh grille to improve airflow within the system without restricting air pressure in an extra-silent mode of operation. 

For affordable, no-nonsense functionality, grab the Corsair Obsidian 750D Airflow Edition and let your gaming PC’s performance speak for itself.


  • Premium build quality at an affordable price
  • Excellent fan support
  • Lots of storage mounting options
  • Improved airflow


  • Can be too aesthetically plain 
  • Cable management can be a bit messy

Lian Li O11 Dynamic XL

Another premium full tower case that can go head to head with the best in the business is the Lian Li O11 Dynamic XL. This case has a dual-chamber design that completely separates the main components of the PC from the power supply and the cables to emphasize aesthetics without sacrificing airflow or functionality. It is designed with maximum water cooling customizability in mind, albeit being limited at 360 mm radiators – but does that really matter when you can fit three of those in this baby? That’s right, the top, front, and bottom panels are optimized so you can run a triple 360 mm radiator in your custom loop.

You can augment its cooling setup as you can install up to ten 120 mm fans with ease. Storage comes aplenty as well, with the four 3.5-inch HDDs that you can hot-swap even when the machine is on, and up to eleven 2.5-inch SSDs. Moreover, the interior is designed to take in even some of the longest graphics cards in the market – accommodating models up to 446 mm in length. 

Other functionalities include a populated front panel consisting of four USB 3.0 and one USB 3.1 Type C port for quick and easy access, while the M|C button allows you to control the addressable RGB strip via several modes, the eighth of which allows it to be synced with the motherboard’s own lighting controls. All in all, the Lian Li O11 Dynamic XL is one of the high-end full tower cases that don’t just pack the looks, but amazing features as well.


  • Spacious internals
  • Neat design
  • Impressive water cooling support
  • Premium construction


  • Fingerprint magnet
  • Heavier than most full tower cases

DeepCool MATREXX 55 V3

If you’re one of those bargain hunters who revel in older or rare pieces of computer hardware, chances are you won’t spend much in the case department either. Worry not, as the DeepCool MATREXX 55 V3 is the cheapest option on our list. Of course, the manufacturer has cut corners to bring down production costs, but that doesn’t mean that this case can’t compete in the big leagues.

For starters, the DeepCool MATREXX 55 V3 has great aesthetics thanks to its additional tempered glass implementation on the front panel, which has an RGB lighting accent on the side for extra flair. It doesn’t sacrifice airflow with this design as well thanks to the side and bottom vents. As for the interior, the case keeps it simple with a standard layout that can accommodate E-ATX to mini-ITX motherboards thanks to its lack of front-loading drive bays, which are now situated in the power supply shroud.

The case is quite spacious as well, contributing to decent overall airflow, although take note that the case has limited watercooling capabilities. You are most likely stuck with closed-loop coolers of up to 360 mm, as the lack of radiator and reservoir mounting points will not allow you to deploy a custom loop in the DeepCool MATREXX 55 V3. That being said, this case has all you need for a straightforward gaming PC build in a full tower configuration without busting the bank.


  • Spacious internals
  • Decent airflow
  • Super affordable 
  • Tempered glass design improves aesthetics


  • Limited water cooling support
  • Low storage accommodation
